SHOCK ABSORBING BUFFER ASSEMBLY Abstract of the Disclosure An elongated one-piece plastic grid of longitudinally extending cells provides a resilient primary energy-absorbing medium in a buffer assembly which projects from a vehicle body for absorbing impact forces to minimize vehicle damage. Differ- ing cell sizes, cell wall thickness, and cell wall draft angles are provided to optimize resistance to penetration and force transmittal levels. The grid has front and rear mounting walls at the ends of predetermined cells to facilitate grid attachment to a backing beam and to provide walls for the attachment of a spreader plate assembly that distributes localized impact forces to a large number of cells to reduce impact penetration. A thin walled flexible plastic facia, fitted over the spreader plate assembly and over horizontally extending wing portions of the cellular grid protects the grid and provides for a finished appearance.
